It would appear that the Red Cross in Red Circle and the Patch management warning shown above means that the device has not finished its patching routing i.e. either the client has not restarted or has been postponed by the end user.@colinjones could this be your issue?
We think we’ve found an issue with the WSUS server on the network. We’ve disabled WSUS and reset the endpoints to search online for updates rather than the WSUS server. Seems much better now.
We will wait for the outcome of the test you have done. In case the issue is still not resolved. Please reply to the ticket we have created in order for us to investigate further.
